The disclosure is directed to a method to generate a generated stereoscopic video image stream of a zenith or nadir view perspective of a scene utilizing a blending of stereoscopic and monoscopic view perspectives. In another aspect, a system is disclosed for generating a zenith or nadir view perspective utilizing a relative user view orientation. In another aspect, an apparatus is disclosed capable to generate a zenith or nadir view perspective utilizing a detected user view orientation, and display a generated stereoscopic video image stream of the view perspective.

What is claimed is: 
     
       1. A method generating user view perspectives of scene images captured by multiple cameras, comprising:

 selecting a first video image stream and a proximate second video image stream, from said scene images, that proximately represent said relative user view orientation, wherein at least one of said video image streams is a zenith or nadir user view perspective of said scene images; and 
 stitching together, to generate a generated stereoscopic video image stream for said user view perspective, said first video image stream and said second video image stream, utilizing a proportionate blending of a monoscopic view perspective and a stereoscopic view perspective, wherein said proportionate blending is proportionate to said relative user view orientation and said first video image stream orientation and said second video image stream orientation. 
 
     
     
       2. The method as recited in  claim 1 , further comprising:

       8. The method as recited in  claim 1 , wherein said stitching includes increasing disparity between said first video image stream and said second video image stream utilizing said user view orientation, whereby said user view orientation approaches a mid-point between said first video image stream's in-line view direction and said second video image stream's in-line view direction. 
     
     
       9. The method as recited in  claim 1 , wherein said stitching includes increasing a stereoscopic view perspective of said first video image stream and said second video image stream, when said user view orientation is equal to or greater than 35%, and equal to or less than 65%, of a distance between said first video image stream's view direction and said second video image stream's view direction. 
     
     
       10. The method as recited in  claim 1 , wherein one of said first video image stream and second video image stream is adjusted to substantially align said one of video image stream with other of said video image stream, where said adjusted includes at least one of rotation, tilt, scale, and shift. 
     
     
       11.
